A convicted murderer and rapist was executed by nitrogen gas on Thursday — 14 years after he was transferred to Alabama while serving a life sentence in Michigan for a separate murder. Demetrius Frazier became the fourth inmate in the US to be put to death by the method as he served his sentence for the 1991 murder of Pauline Brown at the Holman Correctional Facility.

Demetrius Terrance Frazier was the fourth person executed in the United States using nitrogen hypoxia, which involves replacing breathable air with pure nitrogen gas

It is Alabama’s first execution for 2025 after having led the nation in 2024 with six executions -by either lethal injection or nitrogen gas.
